Identified - We are currently seeing very high load on our Cumulocity IoT Platform at cumulocity.com

The high load is on the database which will impact everyone using the platform - you can see 502 errors when logging in, or your microservices not responding in time.

We have located the source of the high load and applied request limits.

Further actions might still be needed.

We are continuously monitoring the Platform and will keep you updated with further information.

Apologies for the inconvenience caused.

Identified - With the 10.10 release, the cipher suite was updated and weak cyphers were excluded to make the platform more secure.
This was announced latest in the 10.9 release notes, but because a lot of active devices are still using old ciphers, we are looking for a possible solution supporting older ciphers.

There are two separated paths here based on protocol:

* HTTP - it is already possible to configure ciphers per instance, for now on all environments (emea, eu-latest, apj and us) we decided to use configuration from version 10.9, exception is our cloud instance where TLSv1 was disabled. The main point here is that we are quite flexible in this field and we can change those configuration with low effort.

* MQTT - with version 10.10 platform was moved to containerised core environment, where mqtts traffic is terminated, which makes the ciphers configuration a little bit more complex. We are investigating possible solutions here.

Also note that MQTT devices with old version of the paho library will not be able to connect using TLS v1.3
